SEE-GIFICATION forming part of Letters Patent No. 685,939, datedNovember 5, 1901.

Application iiledrOctober 17, 1899. Serial No. 733,871. (No modell) Toall whom, it may concern:

Beit known that we, GUIDO PALAZZI, UGO PALAZZI, and VITTORIO PIVETTA,subjects of the King of Italy, residing at the city of Naples, in theKingdom of Italy, have invented certain new and useful Improvements inHyp thereto, a closed vaporizingfchamber above y the heating-burner, asoldering-burner in communication with a second gas conduit or pipe, agassupply pipe in communication with the gas conduits or pipes, avapor-blowpipe in communication at one end with the upper part of thevaporiZer and at the other with the soldering-burner, and a spring-valvefor regulating the flow of gas opened by finger-pressure, located ineach of the gas-pipes leading to the burners.

Such invention is fully shown in the following specification, of whichthe accompanying drawings form a part, wherein similar letters I ofreference designate like or equivalent'parts i wherever found throughoutthe several views, and in which-- Figure l is a side View of theapparatus. Fig. 2 is a top View thereof. Fig. 3 is a vertical sectionalView of the same on the line X X of Fig. 2. Fig. 4t is a sectional Viewin detail, on an enlarged scale, of the valves on the line Y Y of Fig.2.

Referring to the drawings, the referenceletter ct indicates the handleof the solderer, and through its hollow interior passes the gaspipe b.This pipe divides into two branches where it leaves the handle andimmediately before the main valves c d. The valve d is placed in thelower pipe e and the Valve c in the upper pipe, which beyond such valve`o also divides into two parallel branches g g,

which each communicate at the front of the apparatus with a single pipe72., which is bent downward, so as to give a convenient direc- .2 tionto the iiame, the burner 7c being located at the end thereof.

The regulatingvalves c and CZ consist of a piston S, having annulargas-grooves u and o, which pistons are forced outward by a spiral springT and inward by finger-pressure exerted upon the head or nger pieces.The two valves differ in that in its normal position the valve c fullycloses its conduit or pipe, so as to absolutely stop the flow of gastherethrough, while the valve CZ in this position allows a littlepassage to remain always open to the gas-stream in the pipe or conduite, the groove o being arranged in such a way that a small portion of italways forms a free communication between the conduit or pipe e and itsbranch of thepipe b.

The pipe e extends to the front of the apparatus and turns down in ahookf, by which the device may be hung up. At about the middle of thepipe e and immediately under the water-reservoir q is a burner orburners m. The pipe e ends in a finely-pointed tube or pipe n, whichruns along the tube 7e and terminates with a very small hole under theburner lo, acting as a pilot-light therefor.

Inside 4the tube h or pipe is another smaller pipe or tube p, with openends terminating in the interior of the burner 7c at one end and at theother in the upper part of the small reservoir or boiler q, which formsthe vapor or blowing pipe of the device. This boiler is usually ofcylindrical form, with rounded ends,having at its upper part an aperturer, with a screwed cover, through which the water or alcohol to bevaporized may be poured.

To operate the device, the reservoir or boiler q is filled abouthalf-full of water or alcohol and the top screw r screwed tightly down,so as to make suoli boiler air-tight, save through the vapor or blowingpipe p. The tube b is then connected to the gas-pipe Figs. 1 and 2, andwhen the gas-cock has been opened the gas passes through the smallpassage, which the groove o of the valve ol always leaves free, andiiows from the burner m and from the small pipe n at the burner la, andthese being 1 lighted the solderer is ready to be put to use.

To use it, the valve d is pressed inward in IOO such a Way as to bringthe groove n in regis-` try With the opening of the conduit or pipe e inorder to allow the greatest possible quantity of gas to flow throughsuch pipe eto the burner m, which raises the Water in q to theboiling-point, and as soon as the jet ot' steam flowing from theblowing-pipe p is of sufficient force the valve c is pressed inwarduntil the groove u comes in registry with the opening of its conduit orpipe and allows free passage of the gas through the tubes g and g lo thepipe h, and at the aperture of the burner la the gas meets thepilot-'dame n and is thus lighted, whereupon the apparatus is ready forWorking by directing the pencil of flame upon the article to be solderedor heated.

Thejet or pencil of 'flame may be regulated by pressing upon the valvesc and CZ.

ofthe burnerm,and consequentlythestronger the blast, and the greaterthat on d the greater the flame of the burner 7c. j

When the soldering is terminated, the valves c and d are released fromfinger-pressure, Whereby the flame of the burner 7c is eX- tinguished,and at the same time the flames of the burner m and of the smallpilot-light 'n are diminished.
